tively Wide strips as land betweentl'ierowsundisturbed. This is an important feature in planting in relatively dry and sandy-so ls the surface of which, if cultlvated, isreadily blown away in windy weather, the seed often being carried away with thesoil.

Another important feature of the invention resides in universal mounting 'vfor the disk shafts of the different which mountings render the machine flexible and "enable the disks toenter the soil at uniform depth on level or un-level ground. This rea ture also lightensthe draft of the machine andenables the disks of the different gangs to be readily adjusted to different angles to cut to different depths. e

Other features will hereinafter appear, and in-order that the invention may be fnlly understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a broken-plan view of the mach ne. Fig. 2 is a sideelevation of the machine. Fig. 3 is an enlarged broken sectional View of a portion of one of the gangs.

Fig. 4 is a vertical section on line IV.IV 0fFig3. r

Fig. 5 is a detail plan now of a draft connection employed in carrying out the invention. I

In the preferred construction of the machine, four gangs of disks 2, 4, 6 and 8, are

employed and each gang is capable of a certain amount of independent vertical move ment which enables the disks of the different gangs to accommodate themselves tonnground and'form furrows of uniform depth. i i

As all of the gangs are substantially alike, excepting that the two rear gangs ,6 and 8 are equipped with the seed sowing mechanism, I will proceed to describe the two rear gangs in detail. The disks 6 and 8 are of concavoconvex form in cross section and those of each gang are mounted upon a square shaft 12, which they rotate by reason of their contact with the soil.

The disks of each gang are spaced apart by journals14, Fig. 3, which have square bores to receive the shaft 12 in order to be rotated thereby. uts and washers l6 and 18, respectively, on the ends of the. shaft 12 hold the disks 6 and the journals 14 in assembled position. The ournals 14 are flanged at each end as indicated at 20 to overcome any tendency of the disks 6 to wabble on the shaft 12, and each journal 14 is mounted in a hearing 22' formed in two longitudinal halvesremovably connected by bolts 24, so that they maybe readily placed in position removedtrom said ournals 14. i

The ournals 14, are provided near their upon or ends with leather or other suitable gaskets 26 toretain a lubricantin the bearings'QSZ and also to exclude dust. .Each bearing 99 is secured. to the lower ends of a yoke 28 and the yokesof each gang are firmly united nel or other bar 30.

at their upper portions by meansof a chanin order that the gangs 6 and 8 may rock longitudinally and "independently of each other to accommodate themselves touneven ground and permit of their adjustment to different anglesrelative to the forward travel of the machine, said gangs 6 and 8 areflexibly connected by an arch32, boxes 34 secured to the lower portions of said arch 32, straps 36, and balls or spherical. protuberances 38, F 3 and 4, one'of which is formed integral with or otherwise secured to one bearing 22 of each gang. The boxes 34 and the straps 36 are connected. by'suitable means such as bolts 40, and have concave surfaces to fit the associate ball 38, so that the same may turn in any direction. Each ball 38 has an'annular recess 42 to receive a-circular shoulder 44 on the associate ournal 14 to prevent the same from moving longitudis' nally and coming 1nto undue frictional contact with the disks at the ends of said ournal.

their lower ends to brackets 50,.so as not to in their sockets.

The arch 32 is rigidly secured at its upper central portion to a forwardly extending beam 52 provided at its forward end with a clevis 54 to receive a pivot 56 whereby it is connected to a coupling on the rear end interfere with the movement of said balls 38 braces 46, 4. Braces i of the beam 52 of the forward gangs 2 and 4. A ball Washer 53 carries the pivot 56 to enable the same to turn in any direction in the couplin and thus afford a flexible connection between the forward and rear gangs. The arch 32 is further connected to the beam 52 by means of draft-bars 58 secured at their rear ends to the ends of said arch 32 and at their forward ends to the forward portion of the beam 52, Figs. 1 and 2. Suitable means such as bolts 53 are employed to connect the arch 32, the braces 46, the brackets 50, and the draft-bars 58 together.

In order to cause the disks to out furrows at the desired depth the gangs are adjusted obliquely to the line of travel of the machine as indicated by dotted lines, Fig. 1, through the intermediacy. of hand levers 60 and connecting bars 62. The hand levers 60are fulcrumed on pivots '64, secured to the beams 52 of the forward and rear gangs, while the connecting bars 62 are,preferably, connected at their forward ends to their respective hand levers 60 and at their rear ends to U- shaped members 66 one of which is mounted on a bearing 22 of each gang. By connecting the hand levers 60 through the intervening mechanism to the adjacent ends of each pair of angs and locating the balls 38 and their socfiets at approximately midway between the ends of each gang it is apparentthat the gangs can be adjusted to different angles as above stated without undue exertion on the part of the operator.

In some instances thefront and rear sections of the machine may be uncoupled and used independently of each other, but more eflicient results can be had by using the complete machine.

From the foregoing description it will be understood that I have produced a machine well adapted for the purpose intended and while I have shown and described the pre ferred embodiment of the invention, I reserve the right to make such changes in the construction, combination and arrangement of parts as properly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent,

In a machine of the character described, two gangs arranged at opposite sides of a central draft line and consisting of rotary disks, journals spacing the disks of each gang apart, bearings in which said journals are mounted, a box in which one bearing of each gang has universal movement to allow free movement of the respective gangs, an arch ri idly connected at its ends to said boxes, a forwardly projecting beam rigidly connect ed to the central portion of said arch, draft bars rigidly connected at their ends to the preventing independent longitudinal movement of the latter, box in which one bearing of each gang has universal movement to allow free movement of the respectivevgangs,
